## Description

DONGKER Optocoupler Isolated Module,DC 24V to 5V 8-Channel Optocoupler Relay Module PLC-PNP Signal Converter: desertcart.com: Industrial & Scientific

Review: Great industrial component - It works as intended and keeps 24 and 5 volts isolated. Just realize that that the 5v output is normally closed circuit. so when 24 is applied, it opens the circuit.
Review: Keeps voltages separated - Husband is using this device to keep the voltages separate so he doesn't burn up his Raspberry PI. It's been working very well for him.

## Features

- Its working frequency is 20KHz,which can be used for signal isolation and polarity reversal.
- It has a working status indicator and a power indicator,which can directly see the working status of the module.
- It has a variety of different connection circuits.
- It comes with a housing and can be mounted on rails.

### ⭐⭐⭐⭐⭐ Keeps voltages separated

### ⭐ Review
*by M***F on January 6, 2026*

Die Verpolungsschutzdiode liegt parallel zu VCC und GND. Verpolt man aus Versehen die Versorgungsspannung wird diese durch die Diode kurzgeschlossen. Das ist nicht Sinn und Zweck einer Verpolungsschutzdiode.
